WHAT’S TO COME? What is the new danger? Where is the danger coming from? What creature is the danger coming from? Is there any way to stop this danger?
MALARIA What is Malaria? An infectious disease transmitted to humans by female mosquitos Symptoms include fever and headache and can lead to coma or death Flickr
MADAGASCAR Surveys/Tests “10% of the people they(the researchers) tested who had vivax malaria were “Duffy-negative,” meaning they lack the Duffy proteins on the surface of their red blood cells to which vivax malaria parasites attach.”...confusing? EVOLVING! People that were Duffy-negative were thought to be nearly immune to malaria 95% of Africans are Duffy-negative
2 MAJOR TYPES OF MALARIA Vivax Malaria Not as lethal as Falciparum Malaria Harder to cure Falciparum Malaria Caused by a different parasite Not affected by Duffy proteins Kills about 650,000 people per year, mostly in Africa
FEARS COMING INTO REALITY Is vivax evolving into a falciparum-like parasites? From research: No obvious mutations or abnormalities.
KEY POINTS 1.Malaria is transmitted via mosquitos. 2.Key research is being conducted in Madagascar. 3.The most violent form of malaria kills about 650,000 people per year. 4.95% of Africans are Duffy-negative due to sickle-cell anemia. 5.Vivax malaria is not as lethal but is much harder to cure then falciparum malaria.
